We are interested in installing the latest possible Perl version on our Solaris 10 servers. Does anybody have any recent experience? I would like to know which latest stable Perl version would work on Solaris 10 and what are any known caveats.

I would suggest installing perlbrew https://perlbrew.pl/ which will give you the ability to easily install multiple versions. You can start by installing 5.10 then start moving up the version chain until you run into problems.

Thank you all for responding. We have 5.10.0 installed and we have some means for swamping between Perl versions. 5.10 is an unsupported version for a decade now and I really want some current version. I will try to build to 5.28.0 in parallel to the 5.10.0 and see how it goes. If there are any issues I'll fall back to 5.26 and if that does not work I may give up altogether. I'll report here if it worked. ZA
